Zener TVS diode, 5KP series, order code 5KP170A, unidirectional 1-channel, 170 V reverse standoff, 189 V minimum breakdown, 275 V clamping, 18.5 A peak pulse, 5000 W peak pulse power, P600 axial package, through-hole mount, -55°C to 175°C junction operating temperature.","salesMarkdown":"## 5 kW peak pulse — the defining rating The 5KP170A: At that peak pulse current of 18.5 A, the clamping voltage sits at a maximum of 275 V — the protected rail therefore sees an upper bound of 275 V during a surge event, so downstream circuitry must tolerate that clamp ceiling or the TVS itself does the job. ## Axial P600 and the wide temperature envelope The P600 axial package is a through-hole part — it mounts directly into a PCB and conducts heat through the lead frame into the board copper, so thermal relief pad area and lead dress matter more than the housing itself for sustained performance. The -55°C to 175°C junction temperature rating is unusually wide for a general-purpose TVS; it covers the full industrial range and extends into automotive-adjacent or outdoor-equipment environments where ambient spikes push junction temperatures higher than a standard 150°C part would allow. ## Standoff, breakdown, and the protection window Because the 5KP170A is unidirectional and single-channel, it protects one polarity only — for AC lines or dual-polarity rails a bidirectional TVS would be required; this part suits DC supply rails with a known polarity.","metaTitle":"Littelfuse 5KP170A TVS Diode, 5kW Peak Pulse","metaDescription":"Littelfuse 5KP170A unidirectional TVS diode, 170 V standoff, 5 kW peak pulse.
